Belt. It is best to bring a computer with you for business training. If you have your own laptop, you'd better take it with you for business training. Usually on the way to a business trip, if the company has something to deal with, it is convenient to get computer information and work in the computer in time. At the same time, when you arrive at your destination, the business trip training will also record some related things in the computer and take notes on the business trip training. So try to take your computer with you when you are on a business trip.
